### Description

I was testing out rocketchat on android. I ran into the issue where I get the error message:

> java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

I read a few other issues where this popped up on an older version of rocketchat but nothing recent. None of the older ones were solved.

I do try and click on the _Apply Your Certificate_ link but it does nothing.

Hi, i had the same problem wheni use my own certificate with caddy.  
I would have to deploy the crt certificate on the mobile device ; PEM and KEY was declare in the caddy file.  
But, it’s NOT a godd solution for people outside my company ; so i use the letsencrypt and auto renew certificcate (which doesn’t works since 2 week …)

Bonjour,

Je suis actuellement dans le même cas!!!  
Certificat autosigné, mais impossible de pouvoir me connecter a mon serveur avec un Android, alors que pour un IOS cela fonctionne correctement.  
Que faire?

Bonjour, je n’utilise pas de certificat autosigné mais nos propres certificats wildward payants  
le https est géré par Caddy comme la doc le préconise.  
Pour utiliser nos certificat wildcard, la commande **TLS moncertif.crt moncertif.key** a été rajouté dans le fichier caddyfile  
Cela dit, le crt à lui aussi été modifié afin d’inclure la chaine complète ; le crt doit inclure le contenu du cer (ou du crt) **ET** du chain et là tout roule ; plus d’erreurs android
